@nChauhan91 i might need cookies or creds of an account to reproduce and fix the issue as i can't reproduce it with the courses i have in my account.

the otherway could be finding a course which is free and produces the same issue so that i can enroll and check against that.

for courses that i have in my account, udemy-dl is working fine for me.

okay you can take my account: access_token = ****

and try to use this command:

python3 udemy-dl.py https://www.udemy.com/course/web-development-masterclass-complete-certificate-course/learn/lecture/5770596?start=45#overview --skip-sub -k cookie.txt.txt

@xalgord thanks for sharing your cookies you could have shared it on my email though. never share such things publicly as i will not be responsible for misuse its just an advice i have edited the comment, you can re-login or update password so that the access-token gets changed as using this token anyone with udemy-dl will be able to download all courses from your account without your permission.

my email is also listed on profile: logout and login back again and share the new access_token over email nasir251292@gmail.com,

If privacy is no concern for you then it's okay i will continue testing with the access token you provided and you don't need to change anything. the token will expire soon though but i have checked for me the token even worked for days. (never checked expiry time)

Has this been fixed? I also get issue on this course: https://www.udemy.com/course/react-the-complete-guide-incl-redux/
It doesn't download anything from Section 2: JavaScript Refresher and is skipping some other videos on Section 3 as well. Can't remember exactly on top of my head.

This question was made exactly for this course & chapter 😁

I have found another course with same problem i think
udemy.com/course/the-complete-guide-to-angular-2/

I noticed that the ones it skips for me are also disabled for download on the udemy site.
i.e the download button is greyed out for those courses
